The variables with P < 0.05 in the above univariate analysis underwent multivariate logistic regression analysis. The results showed that pre-existing gallbladder disease, clinical classification, initial TBIL, initial PT, and initial title of ANA were the independent risk factors for DILF (Table 4). M (IQR): median (interquartile range); n (%): number of cases (percentage); -: none
